- SCREEN.

Application filed September 29, 1921. Serial No. 504,134;

' To all whom it may concern:

Be it known that I, HUGO J AEGER, a citizen of the United States,residing at Schenectady, in the county of Schenectady,

State of New York, have invented certain new and useful Improvements inScreens, of which the following is a specification.

One of the objects of my invention is to rovide a simple constructionfor screen rames whereby the side members of the frames may be securelyfastened together at the corners.

A further object of my invention is to provide a corner construction forscreen frames which will be strong and which will have no portions whichare thicker than the side members or which project beyond the oppositeplanes of the side members.

The novel features which I believe to becharacteristic of my Inventionare set forth with particularity in the appended claims. My inventionitself, however, both as to its organization and the manner in which itis carried into effect will best be understood by reference to thefollowing description taken in connection with the accompanying drawingsin which Fig. 1 is an elevation of one corner of a completed screen;Fig. 2 is a perspective of the separate members making up one corner ofa screen; Fig. 3 is a perspective of one corner of a screen with theparts assembled; Fig. 4 is a perspective of one end of a frame memberillustrating one step in the process of manufacture, and

Fig. 5 is an elevation of a complete screen.

As indicated in the drawings, a screen constructed in accordance with myinvention comprises U-shaped side members 1 and 2 which embrace theedges of a perforated sheet 3. Inthe case illustrated where a finescreen of rigid construction is desired the perforated sheet 3 issupplemented by a fine mesh screen 4. It will of course be understoodthat either a perforated sheet or a woven screen may be used separatelyand in the descri tion and claims which follow I employ t e termperforated sheet or similar phraseology to include either of theseconstructions as equivalents.

In constructing a screen the curved portion and one of the side portionsof each end of the U-shaped members is cut away, as indicated in Fig. 4.In assembling the screen members the remaining end portion 5 of member 1is fitted into the space formerly occupied by the cut away portion ofmember 2, and the remaining end portion 6 of member 2 is fitted into thespace formerly occupied by the cut away portion of member 1. The end ofthe remaining portion 5 of member 1 is bent, either before or after theparts are assembled, to form a curved portion 7, which, when the partsare assembled, forms a continuation of the curved portion 8 of member 2.Similarly, the end of the remaining portion 6 of member 2 is bent toform a curved portion 9 which forms a continuation of the curved portion10 of member 1. The small projecting portion 11 of member 1 is then bentover, as indicated in Fig. 3, to form a continuation of the curvedportion 9 of member 2 and the curved portion 10 of member ,1. Similarly,the small projecting portion 12 of member 2 is bent over to form acontinuation of the 7 curved portion 7 of member 1 and the curvedportion 8 of-member 2.

By the construction described the two adj acent side members aresecurely and rigidly locked together. Corresponding sides of adjacentside members lie in the same plane and all of the material at the cornerof the screen is disposed within the two parallel planes of oppositesides of the frame.

While the interlocking arrangement of the side members at the corners issuflicient to hold them in place, they may, if desired, be additionallysecured by a rivet 13 or in any other convenient manner. In order toeliminate the raw edges at 14, as indicated in Fig. 3, these edges maybe stamped or hammered to form a well rounded corner, as indicated at 15in Fig. 1.

What I claim as new and desire to secure by Letters Patent of the UnitedStates, is 2-- 1. A screen comprising a sheet of perforated material andU-shaped members embracing the edges of said sheet, each of said U-shaed members having similar portions at eac end cut away, and theremaining 100 end portions of adjacent members at each corner of thescreen being interlocked.

2. A screen comprising a sheet of perforated material and U-shapedmembers embracing the edges of said sheet, each of said 105 U-shapedmembers having similar portions at each end cut away, and the remainingend portion of adjacent members at each corner of the screen beinginterlocked in such a way that corresponding sides of ad- 110 inparallel rated material and U-shaped members embracing the edges ofsaidsheet, each of said U'shaped members having similar portions at each endcut away, and the remaining end portion of adjacent members at eachcorner of the screen being interlocked in such a way that correspondingsides of adjacent U-shaped members lie in parallel planes, and all ofthe remaining end portion of one member is disposed in such a way as toform a continuation of a portion of the adjacent member.

4. A screen comprising a sheet of perforated material and U-shapedmembers embracing the edges of said sheet, each of said U-shaped membershaving similar portions at each. end cut away, and the remaining endportion of adjacent members at each corner of the screen beinginterlocked to form a continuation of the channel in each of theadjacent U-shaped members.

5. A frame member for a screen comprising a U-shaped member having ateach end one of its sides and the curved portion cut away and the end ofthe remaining said portion bent to form a curved portion extending at anangle to the curved portion of the U-shaped member.

6. A frame member for a screen comprising a U-shaped member having ateach end one of its sides and the curved portion cut away and the end ofthe remaining said portion bent to form a curved portion extending at aright angle to the curved portion of the U-shaped member.

7 A screen comprising a sheet of perfo rated material and U-shapedmembers embracing the ed es of said sheet, each of said U-shaped mem ershaving at each end one of its sides and the curved portion cut away andthe remaining end portions of adjacent members at each corner of thescreen being interlocked.

8. A screen comprising a sheet of perforated material and U-shapedmembers embracing the ed es of said sheet, each of said U-shaped mem ershaving at each end one of its sides and the curved portion cut away andthe remaining end portions of adjacent members at each corner of thescreen being interlocked in such a way that corresponding sides ofadjacent U-shaped members lie in parallel planes.

9. A screen comprising a sheet of perforated material and U-shapedmembers embracing the edges of said sheet, each of said 'U-shapedmembers havin at each end one of its" sides and the curve portion cutaway and the remaining end portions of adjacent members at each cornerof the screen being interlocked in such a way that corresponding sidesof adjacent U-shaped members lie in parallel planes, and all of theremaining end portion of one member is disposed in such a way as to forma continuation of a portion of the adjacent member.

10. A screen comprising a sheet of perforated material and U-shapedmembers embracing the edges of said sheet, each of said U-shaped membershaving at each end one of its sides and the curved portion cut away andthe remaining end portions of adjacent members at each corner of thescreen being interlocked to form a continuation of the channel in eachof the adjacent U-shaped members.

11. A screen comprising a sheet of perforatedmaterial and U-shapedmembers embracing the edges of said sheet, each of said U-shaped membershaving at each end one of its sides and the curved portion cut away, theremaining end portions of each member being disposed in the cutawayspace of the adjacent member.

12. A screen comprising a sheet of perforated material and U-shapedmembers embracing the ed es of said sheet each of said U-shaped mem ershaving at each end one of its sides and the curved portion cut away,

the remaining end portions of each member being disposed in the cutawayspace of the adjacent member in such a way that corresponding sides ofadjacent U-shaped members lie in parallel planes.

13. A screen comprising a sheetof perforated material and U-shapedmembers embracing the edges of said sheet each of said U-shaped membershaving at each end one of its sides'and the curved portion cut away, theremaining end portions of each member being disposed in the cutawayspace of the adjacent member to form a continuation of the channel ineach of the adjacent U-shaped members.

1 1. A screen comprising a sheet of perforated material and U-shapedmembers embracing the edges of said sheet each of said U-shaped membershaving at each end one of its sides and the curved portion cut away, theremaining end portions of each member being disposed in the cutawayspace of the adjacent member and the ends of the remaining end portionof each member being bent to form a continuation of the curved portionof the adjacent member.

In Witness whereof, I have hereunto set my hand this 28th day ofSeptember, 1921.

HUGQ J AEGER.
